This invention relates to a rolling mill for producing strands ofelongated cross-section and particularly to the control for a millespecially adapted for use in combination with the weaving head of aweaving machine capable of weaving ller strips of elongatedcross-section into a fabric with the major surfaces of said ller stripspositioned at an angle to the plane of the fabric.

It is an object of this invention to provide a novel arrangement ofcontrol mechanism for the means that drives the rolls of the above typeof mill whereby .to eifect the initiation of the rolling operation inthe proper sequence with respect to the weaving head operation. It is afurther object to provide in this type of arrange-l ment, meansindependent of the initiating means for maintaining in operation theroll driving means and further, to provide for the release of thisholding means in accordance with the length of material formed.

I describe the warp wire supply assembly and the weaving head assemblyin the detail necessary to bring out the novel combination including myrolling mill and control assembly, however, these structures per se arenot my invention but are covered by Patent 2,223,317 of one Walkley B.Ewing, and Patent 2,214,054 of one Max P. Heinze, filed simultaneouslyherewith. My invention is directed primarily to a novel rolling millstructure including the control mechanism therefor and particularly tosuch an arrangement applied to the `problem of supplying filler strandsto the weaving head as described and pointed out in the appended claims.

Turning to the drawings wherein there is illustrated a weaving machinewith which my rolling mill and novel control is particularly adapted forcooperation, there is shown in Fig. 1 a weaving head assembly indicatedgenerally at A; a Warp wire supply assembly indicated generally at B;and a filler wire forming an injecting assembly indicated generally atC.

The weaving head A comprises essentially a comb assembly indicatedgenerally at l0 (see Figs. 3 to 9) formed with a plurality of guidewaysII (see Figs. 8 and 9) for guidably receiving ller strands I3 ofelongated cross-section crosswise of a corresponding number of pieces ofcloth being simultaneously woven and for holding the same with theirmajor surfaces disposed at a predetermined angle to the planes of therespective pieces of cloth. The comb assembly is further speciallyformed adjacent the guide and holding means II for cooperation with twosuperimposed rows of rotatable quills referred to generally at I and I6,the function lof which is to feed a plurality of uniformly spaced pairsof warp wires I'I about the ller strands I3 and to twist the respectivewarp wires of each pair of warp wires together to form interlockingtwists I9 (see Fig. 8) for securely fastening the filler strands inposition in their respective fabrics. The guide and holding means II isfurther arranged to be subsequently opened for advancing and releasingthe filler strands preparatory to again being moved to a positiontherebehind for receiving additional filler strands I3 in said guidesfor likewise being tied into the cloth by again rotating the quills l5and Iii. Power means is provided in the form of motor driven cams andlevers (see Figs. 4 to '7) for effecting the operation of the weavinghead assembly in the proper sequence. While I have shown the weavinghead as having two guides II together with corresponding rows of quillsfor Weaving two pieces of cloth simultaneously, this is merely forillustration and it will be apparent that a larger number of pieces ofcloth may be simultaneously woven, by merely providing additional guidesII and corresponding rows of geared quills IE. On the other hand, onlyone piece of fabric may be Woven, employing only one guide and one rowof quills.

Warp wire supply assembly B comprises generally a plurality of rotatabletables 2l (Figs. 1 and 3) corresponding in number to the number ofquills, each table supporting a pair of spools 22 and 23 for supplyingpairs of warp wires I7 to each of said quills, these tables being driventhe same total number of revolutions as the quills by motor 2L! (Fig. 1)through reduction gearing 25 and chains 26 whereby to prevent thetwisting together of the warp Wires behind the quills. The warp wirespass from adjacent their respective spools through conduits forpreventing entanglement and for imparting a slight tension to the warpwires,

The mill `assembly C (see Figs. 10 to 14) cornprises generally a pair oftangential iiattening or elongating rolls 28 and 29 driven periodicallyVin sequence with the weaving head assembly operation by a hydraulicmotor Eil. These rolls receive a pair of round wires from stationaryspools 32 and 33 `and flatten the same to form wires I3 of ei'ongatedcross-section and simultaneously inject these wires into the guide andholding means II of the comb assembly above described. This wire is cutoff adjacent the side of the cloth in response to the forward movementof the comb assembly, during the subsequent advance of cloth, by knifeSil carried by the weaving head A and operating in conjunction Withstationary shearing block mounted on the mill frame.

lil/'hilo I prefer this arrangement for cutting on the ller wire sinceit has a number of distinct advantages, I nevertheless contemplate theuse of other well known cutting means as com- `ing within thebroad scopeof my invention, when employed in the combination disclosed, the dislclosures in the patent to Riley No. 1,647,311 and'- the patent to LloydNo. 1,703,276 being cited asA examples of such well known arrangements.

The weaving head indicated generally at If comprises in further detail abackplate 5%, (Fig.' 8) formed with a plurality of vertical slots 5Itherethrough for the passage of pairs of warp wires I 7; a pair ofchannels 52 traversing the forward face thereof and intersectingvertical slots 5I and of the proper size for guidably receiving theribbon-like filler strands I3; and a vertically reciprocable comb 54formed with teeth E5 defining slots 55 therebetween corresponding inposition to slots 5I in backplate 5I). This comb Si is operable on` theface of plate 5E from a position4 wherein the teeth 55 thereof eX- tendup between the adjacent pairs of warp wires I? and in which positionthese teeth are effective to close the channels 532 in the forward faceof plate 5d to define the completed guideways I! above referred to forguidably receiving liller wires i3 of elongated cross-section andholding lthe same at a predetermined angle relative to the plane of thecloth into which these filler wires are to be woven, to a loweredposition wherein the teeth 55 `are withdrawn from the cloth and theforward portions of channels 52 are opened to permit of the retractionof the comb assembly backward to withdraw the channels from about thefiller strands I3 and to again elevate the comb teeth 55 to close thechannels 52 preparatory to the subsequent injection of an additionalller strand therein.

As before stated the interlocking twists between the two warp wires I7of each pair for locking the filler strands I3 in place are produced bytwo rows of quills referred to generally at I5 and i6. The backplate 50is formed with enlarged vertically extending channels 5l converging withvertical slots 5I and serving to admit the forward noses of quills I5,It, to a point closely `adjacent channels 52.

The quills are cylindrical in shape, being journalled adjacent theirforward and rearward portions in bearing plates 58, 5S and gearedtogether for synchronous rotation by circumferentially formed gearteeth. Each quill is formed with a pair of diametrically disposedcoaxial grooves or channels Si) (see Fig. 8) for guidably conveying itscorresponding pair of warp wires from the rear end thereof to points ofdischarge on the forward nose of the quill. These channel guideways passalong the periphery of the quill through the troughs betweensubstantially diametrically opposed pairs of teeth of the quill gear andare brought out in a slight curve lt! to the nose of the quill, thedirection of curvature being gen-Y erally clockwise on all of thequills. The purpose of this arrangement of guideways on the quills is todischarge the respective warp wires of each quill at points lying ondiameters of the quills, all of which diameters lie in parallel verticalplanes at the time of discharge.

Each of the quills is further formed with a wedge-shaped forward nose 62to facilitate its entry into channel 57 to a depth closely adjacent thefiller strands I3 but spaced slightly out of contact with the channelwall with the long edges 63 of noses 6| all parallel and extendingvertically. The guideways 6B discharge the warp wires from the quills atthe opposite ends of the edge 63 o-f the wedge-shaped nose 62, to apreceding interlocking twist lI9 thus defining a shed for the receptionof a filler strand IS.

A drive arrangement is provided for effecting the rotation of all thequills synchronously at successive intervals without releasing drivingcontact therewith. Referring particularly to Fig. 8, the upper row ofquills Ii5 is provided with staggered but overlapping teeth 6.4 `and 55on alternate quills, while the lower ro-w of quills I6 is provided withteeth 66 extending between bearing plates 58 and 59, the gear teeth ofall of the quills being in driving contact. A rack B6 is positioned forengagement rst with teeth 64 of the forwardly geared quills and isarranged to be driven .to the right as indicated by arrow 51 a distancesuicient to rotate the quills 360 in a clockwise direction to produceinterlocking twist between the respective warp wires of each pair. RackB5 is subsequently shifted backwards as indicated by arrow 58 in adirection parallel to the teeth thereon to a position in mesh with theteeth B5 of the rearwardly toothed quills and out of Contact with teeth54, preparatory to the subsequent movement of rack 96 to the left asindicated by arrow 69 to again effect the rotatation of the forwardlygear-ed quills 360 in a resumed clockwise direction to again produce arow of interlocking twists for tying in `a previously injected lllerstrand I3. The rack is subsequently shifted to the front as indicated byarrow I9 to again bring the teeth thereof into engagement with theforward quill teeth 54 to thus complete a rectangular path preparatoryto repeating the cycle.

`Turning next to the power operating means for moving the comb assemblyI backward and forward relative to the quills I and I5 and for causingthe comb 515 to be raised and lowered on the backplate 59 and also tothe power means for effecting .the movement of the rack E6 in the abovedescribed rectangular path, there is provided a plurality of cams drivensimultaneously from a comme-n power shaft, these cams acting upon thenecessary levers through rises and falls on the cams for causing therequisite movements of the parts.

A cam 'II (Fig. 4) is effective to move the entire comb assembly IBforward and backward about pivotal supporting shaft 'I2 by operating onroller 'F3 mounted on the end of link T4, adjustably connected to arm'I5 projecting from the rear of backplate mounting member 15. Backpl-atemounting member I6 is connected to pivotal supporting shaft 'I2 throughthe medium of journals 'I'I carried on the underside thereof, supportinga. transverse shaft 't8 which in turn is connected by a plurality ofsupporting links 'I9 to transverse supporting shaft T2. This shaft inturn is journalled in comb assembly bearing brackets 3i).

A second cam 52 (Figs. 6 and 7) located adjacent cam 'il is effective tocause the vertical reciprocation of comb mounting plate S3 by drivingroller 8l! mounted on the end of link 35, adjustably connected to arm85, pivoted inter-` mediate its ends on pin. 9i, journalled in the abovereferred to arm l5 and this arm 95 acting through roller 88 on theforward end thereof to raise and lower the comb. Comb mounting plate $33is slidably received on the forward face of backplate mounting member'I5 and is provided with a bearing plate 39 (Fig. 2) for cooperationwith Y roller 88, and mounts comb 54 in the upper portion thereof. Thiscomb is made of a high grade of steel and the teeth 55 are machinedtherein to a veryne degree of accuracy.

Actuating cams 'II and 82 are mounted on the same shaft 89 driven from acommon power shaft 90 (Fig. 1) through reduction gearing 25 by electricmotor 24 positioned at the rear of the machine. While I have indicatedonly one cam 'II and one cam 82, I contemplate the use of two each ofthese cams being identical in form and located adjacent the respectiveends of the shaft 89 for the purpose of effecting a better balance inthe operation.

The rollers carried on the ends of links 'I6 and 85 are held in contactwith the corresponding cam by suitable means such as adjustable tensionsprings 15a and 88a.

The means for effecting the shifting of the rack 55 from the forwardgear teeth 5t to the rear quill gear teeth 55 and back again comprisesan upper cam 9! (Fig. 4) having an appropriately formed groove 92therein engaging roller 93 for oscillating forward and backward rackshifting lever 94 mounted on xed pivot 95 and carrying roller 95 on theopposite end thereof in driv- ,ing engagement with rack carrier 91. Icontemplate the use of two of `these cams 9i one adjacent `each end ofthe supporting shaft 98 for the purpose of balancing the operation ofthe machine.

For effecting the movement of rack 56 to rotate the quill gears there isprovided a second or intermediate cam 99 (Figs. 2 and 5) having anappropriately formed cam groove Hl!) in the face thereof for drivingcooperation with the roller lill mounted in one end of a rack drivinglever H32 pivoted intermediate its ends on pin |93 and engaging the rackcarrier 91 through a roller IM carried on the other end thereof fordriving the rack back and forth to eifect rotation of the quills. Cam S9is also mounted on shaft 98, the latter being journalled in brackets |05extending from face casting I 09 and base casting IiiI. Shaft 98 islikewise driven from power shaft 9i! but is connected through areduction gearing whereby cams 9! and 99 are driven at one-half thespeed of cams il and 82. The reason for this, together with anunderstanding of the particular sequence of operation of the abovedescribed elements of my improved weaving machine will be clearlybrought out in the description of operation.

It appears to be sufficient for the purpose of this case to merely statethat at strips i3 are first injected in the guides II of the combassembly I by my novel rolling mill arrangement. The cams 'Il nextbecome effective to move the entire comb assembly slightly forward inorder to give the noses 53 of the quill sufcient clearance in order thatthey may be rotated within grooves 5l. This movement takes placeentirely about pivots '12, the complete comb assembly being shiftedforward.

Cam 99 neXt becomes effective to drive the rack 55 for rotating thequills 360 to produce the integrating twists in the warp wires forlocking the nller wire in place. Following this twisting operation, camTI again becomes effective to produce a further forward movement of thecam assembly for advancing the cloth a short distance while combelevating and lowering cams 92 operate to lower comb teeth 55 frombetween the warp wires and to uncover the channels 52. Cams 'H nextbecome effectiveto retract the cntire comb assembly backward, thusremoving the channels from about the ller wires I3 while cams 82' becomeeffective to again raise the comb teeth 55 to a position between thewarp wires where these teeth again cover the forward portion of channels52 todeiine guideways ti for the reception of an additional ller wire.

Filler ribbon supply assembly and control mechanism therefor The spoolsV32 and 33 of round wire remain stationary, the round wire being drawnfrom the ysides of the spools over guides 2M, 222, thence to a guide2233 on the mill table 26d, from which .it Vis delivered to theflattening faces of rolls y2,53 and 29. A

The spools 32 and 33 may be received in a `cylinder 29| supported on abase 2Mb and provided at its open outer end with a bracket 2Mo`supporting guide 222. This guide preferably is formed by a bar 222erhaving a pair of radially extending pins 222D effective to confine thewire therebetween (Figs. 10 and 1l).

The formation from round wire of filler wire of elongated cross-sectionsimultaneously with the injection of this wire into the shed of thefabric being woven, is important in that among other things, it avoidsthe inconvenience and unsatisfactory procedure of handling and injectingpreformed ller ribbon. This, however. is not my invention.

The stationary supply spool arrangement for feeding the round wire tothe flattening rolls is of particular advantage in the relationdisclosed,

since it renders unnecessary 'the usual arrangement of rotatable spoolsupport and brake there for, and otherwise simplifies this portion ofthe machine. The use of this stationary feed is made possible in thepresent combination by virtue of the fact that the round wire that isdrawn off of the side of stationary spools 32 and 33, even thoughbecoming twisted in being so drawn, the passage thereof through theflattening rolls results in a wire of elongated cross-section that iscompletely acceptable for the present purpose.

Flattening roll 29 is mounted on shaft 2%5 supported in suitablejournals on the mill frame indicated generally at 29S (Figs. 2 and 12).Tangential flattening roll 25 is journalled in a unitary yoke 2M and isgeared to tangential flattening roll 29 through gears 263 and 229. Yoke26'! is supported in guideway 292 (Fig. lfl) for moving flattening roll28 relative to flattening roll 29 in order to control the thickness ofthe elongated strips` The position of yoke 2M is controlled by adjustingscrew Elli for Varying the thickness of the flat ller wire.

The flattening rolls are driven periodically in sequence with theoperation of the comb and quill assembly through a ratchet clutchincluding a rat-chet gear 2|| (Fig. 12) and ratchet 2|2, mounted onplate 2|3 connected to a gear 255; driven by a rack 2 i 5, in turnmotivated by a fluid motor indicated generally at Si).

The fluid motor 32 is of a well known type comprising a reciprocablepiston 2V! connected by a piston rod 2|8 through the usual liquid seal(not shown) to the rear end of the rack 2|5 to which it is in turnfastened by any suitable means such as a threaded connection Zie.

My invention is particularly directed to the following novel controlmechanism in combinan tion with the above structure with which it isparticularly arranged for cooperation.

Fluid power for operating piston 2V! is supplied by a pump 22!) througha two-way valve 22| effective to control the supply of pressure toeither side of the piston depending upon the position of the valve 22|.This two-way valve is under the control of a cam 222 mounted onv shaftV.89 along` with `the comb assembly actuating cams 1| and 32. Cam 222becomes effective at the beginning of the last 180 degrees of-rotationof shaft B9 to depress link 223 which in turn operates bell crank 224 toshift Valve 22| to the right, and thus cause the same to deliver fluidpressure fromcpump 22|) to the rear side of piston 2|?. Bell crank 22f3is further effective to move control rod, 22% against the resistance ofcompression spring 22S to a point where collar 221 carried thereonpermits link 223, urged by spring 223e, to drop in front thereof to thushold control valve 225m the position to which it was moved. Piston 2|?is now subjected to fluid pressure, and drives rack 2|'5 to the left inFig. 12 until cam 23) carried `on the forward end Vof rack 2|5 contactsan upper end of link 228, thus lifting the same out of lock-ingrelationship with respect to collar 221, and permitting spring 229 toshift plunger 225 of valve 22| to the left in Fig. 12, thus changing thedelivery of fluid pressure to the opposite side of piston 2|?, andcausing it to be stopped and returned preparatory to again driving therolls.

The ratchet and pawl 2|| and2|2 operate to drive the rolls `in onedirection only, namely, in the feeding directionand permit of the freereturn of the rack to itsinitial driving position. Provision foradjustment in the operation of locking lever 22S is made by hinging thetwo ends of the lever at `22319 and clamping these two end portionstogether in their adjustedpositions by clamping screw 228e.

It will thus appear that I have provided means for driving thefiattening rolls, the initiation of which is underthe control of cam222, while the continued operation of the same to produce a flat wire ofa given length is under the control of flattening means 223 and cammeans 255i), operable in accordance with the travel of the driving racl:2 l5. This feature is of great importance in the present combination,since it provides assured travel of the rack 2|5 `for the desireddistance necessary to produce a predetermined length of flat wire whichtravel is determined only by the setting of cam 230 relative ,to the endof the rack 2HE. This adjustment may be effected b y any well knownmeans, such, for example, as a clamp-ing screw passing through the bodyof cam 23D and engaging the supporting portion of the rack member 2 5.

While I have shown a ratchet and pawl oneway drive arrangement, it isquite apparent that other forms of one-way drive may be employed, suchfor example, as the well known free-wheeling clutch disclosed in thepatent to Leschhorn, No. 1,684,838.

Adjustment of the rolling mill assembly to provi-de for the properregistry of the discharge guide 23| and cutoff block Se with thereceiving guideways of the comb assembly when the machine is adjustedfor weaving fabric having the flat filler wires locked therein atdierent angles to the plane of the fabric, is provided by theconstruction of the mounting for supporting the mill frame 226 from theweaving head main frame indicated generally at 23S.

This arrangement includes a rst horizontal guideway dening member 23dprovided with a pair of opposed horizontal tongues 235 and 235 adaptedto guidably confine an intermediate adapter member 237. The adapter 25'!is horizontally adjusted along guides 23e, by means of screw 23S underthe control of handwheel 239. Adapter 221 is formed with verticallyconfining guide tongues 241i and 26| for receiving and conning anauxiliary adapter member 242 which is vertically adjustable along guides240, 24| by means of adjusting screw 2i3. Auxiliary adapter 252 hasshaft 244 journalled therein which in turn supports rolling mill frame206. The rolling mill frame is made adjustable about shaft 244 andrelative to auxiliary adapter member 242 by provision of arcuate slotsM5 formed in mill frame member 2% for cooperation With clamping screws2156 passing through these slots and effective to clamp the frame member266 to auxiliary adapter member 242.

It will thus be seen that the rolling mill frame Zi can be readilyadjusted horizontally, vertically and pivotally to bring the deliverychannel of the shearing block 34 into precise alignment with thereceiving guideway channels Il of the comb assembly.

While I have described my invention in connection with one specificembodiment thereof, it is to be understood that this is by Way ofillustration and not by way of limitation and the scope of my inventionis defined solely by the appended claims which should be construed asbroadly as the prior art will permit.
